Opal by Jennifer L. Armentrout presents a unique reading experience that defies traditional storytelling conventions. The narrative isn't a straightforward novel; it doesn’t fit neatly into the genres of paranormal fantasy or similar categories. Readers may find a lack of a well-defined plot or direction, as the story unfolds in unexpected ways without the clarity typical of most stories.

The characters also challenge expectations, as the distinctions between friends and foes are ambiguous. Unlike many tales, Opal does not promise a happy ending, emphasizing the unpredictable nature of life and relationships within the story. This creates a sense of intrigue that keeps readers engaged, despite the absence of typical narrative elements.
